| 摘 要： | 将神经网络技术应用于作物缺水敏感性分析，探讨不同阶段腾发量变化对作物产量的影响。实例分析表明，其分析结果和利用作物水分生产函数分析结论具有很高的一致性。神经网络用于敏感性分析，避免了建立具体的作物水分生产函数模型，而且时空适应性更强，为作物水分－产量关系研究开辟了新的思路。

| Abstract: | Applying neural network technique to analyzing wensitivity of crops' water shortage,effects of evapotranspiration variation on crop production in different stages are discussed.Case study shows that the results well meet the analytical conclusion from using crops' water product function.Using neural network to analyze sensitivity,it allows avoiding to establish concrete model of water product function and has good time space adaptiveness,and develops a new train of thought to sutdy relationship between crops' moisture and production. |
